摘要:
A manufacturing method for a semiconductor device, including forming on or above a semiconductor substrate a silicon film a surface of which has a first polycrystalline silicon film with mushroom or hemisphere-shaped crystal grains, and forming a Ta2O5 film on the silicon film at a pressure of 40 Pa or lower and at a temperature of 480° C. or lower, using a gas obtained by vaporizing Ta(OC2H5)5 as a tantalum source gas.

In a process of forming MISFETs that have gate insulating films that are mutually different in thickness on the same substrate, the formation of an undesirable natural oxide film at the interface between the semiconductor substrate and the gate insulating film is suppressed. A gate insulating film of MISFETs constituting an internal circuit is comprised of a silicon oxynitride film. Another gate insulating film of MISFETs constituting an I/O circuit is comprised of a laminated silicon oxynitride film and a high dielectric film. A process of forming the two types of gate insulating films on the substrate is continuously carried out in a treatment apparatus of a multi-chamber system. Accordingly, the substrate will not be exposed to air. Therefore, it is possible to suppress the inclusion of undesirable foreign matter and the formation of a natural oxide film at the interface between the substrate and the gate insulating films.

After forming a silicon oxide film 9 on the surface of a region A of a semiconductor substrate 1, a high dielectric constant insulating film 10, a silicon film, a silicon oxide film 14 are successively deposited over the semiconductor substrate 1, and they are patterned to leave the silicon oxide film 14 in regions for forming gate electrodes. Then, after fabricating silicon films 13n and 13p by using the patterned silicon oxide film 14 as a mask, when removing the silicon oxide film 14, etching is performed under the condition where the etching selectivity of the silicon oxide film 14 to the high dielectric constant insulating film 10 becomes large, thereby leaving the high dielectric constant insulating film 10 also to portions below the end of the gate electrodes (13n, 13p). Thus, it is possible to ensure the voltage withstanding thereof and improve the characteristics of MISFET.

A main body has a receiving section, which contains an ink ribbon cassette holding an ink ribbon, together with an optical disk. The ink ribbon and the optical disk are fed by a platen roller, and printing is performed on the optical disk through a thermal head. The optical disk is inserted from an insertion port at a side of the main body parallel to the feed direction of the ink ribbon. When the optical disk is inserted from an ejection port in a direction orthogonal to the fed direction of the ink ribbon, an insertion-prevention member prevents the insertion of the optical disk.

A printing apparatus has an apparatus body including a platen roller, a thermal head, a storage in which a ribbon cartridge is stored exchangeably through an opening, and a cover of the apparatus body that covers the opening so as to be opened and closed. A gap is secured between an edge portion of the cover provided for the apparatus body in a state in which the cover is fitted onto the apparatus body to close the apparatus body and an edge portion of the opening of the storage. The gap is a slot for inserting an optical disk in its upright position to the apparatus body.
